Description

Technical Field

[0001] The utility model belongs to the technical field of oil drilling and production, in particular to an oil drilling and production slurry mixing device. Background Art

[0002] In the process of oil drilling, mud is often added to the drilling process to cool and lubricate the drill bit and drilling tools, ensure the stability of the drill bit and drilling tools, and avoid excessive temperature during the drilling process that affects the drilling effect. The mud can also protect the well wall and prevent it from collapsing, thus avoiding the situation where the drilling cannot be used due to the collapse of the well wall. Therefore, the mud plays a certain role in the drilling process, and it must be mixed through a slurry mixing device so that the mud can reach the required state.

[0003] In the process of mud mixing, general mixing devices often use a stirring rod to rotate and stir the mud. Since the mud is heavy, it sinks due to gravity, resulting in slightly different mud concentrations in the upper and lower parts during the mixing process, so it takes a long time to stir it evenly, affecting the mixing efficiency. In addition, there are often large particles in the mud that are not easy to dissolve, which has a certain impact on the mixing. In order to solve the above problems, an oil drilling mixing device is urgently needed to solve the above problems. Utility Model Content
